The elliptic model for social fluxes

Advance Modelling and Simulation of Industrial Boilers

This paper presents some of the results of the simulation in the radiation section of an industrial boiler using an advanced mathematical model. Calculations are described for the flow, heat transfer, and chemical reaction processes occurring within a gas-fired cylindrical furnace. The calculation procedure is a two dimensional one in which the main hydrodynamic variables are the velocity and s...

A NEW PROTOCOL MODEL FOR VERIFICATION OF PAYMENT ORDER INFORMATION INTEGRITY IN ONLINE E-PAYMENT SYSTEM USING ELLIPTIC CURVE DIFFIE-HELLMAN KEY AGREEMENT PROTOCOL

Two parties that conduct a business transaction through the internet do not see each other personally nor do they exchange any document neither any money hand-to-hand currency. Electronic payment is a way by which the two parties transfer the money through the internet. Therefore integrity of payment and order information of online purchase is an important concern. With online purchase the cust...

Numerical Simulation of Separation Bubble on Elliptic Cylinders Using Three-equation k-? Turbulence Model

Occurrence of laminar separation bubbles on solid walls of an elliptic cylinder has been simulated using a recently developed transitional model for boundary layer flows. Computational method is based on the solution of the Reynolds averaged Navier-Stokes (RANS) equations and the eddy-viscosity concept. Transitional model tries to simulate streamwise fluctuations, induced by freestream turbulen...

Experimental Investigation of wake on an elliptic cylinder in the presence of tripping wire

In this research, the behavior and characteristics of the wake of flow in an elliptic cylinder with zero angle of attack in the presence of a tripping wire were investigated experimentally. For this purpose, the used an Aluminum cylinder with an elliptical cross section of the major and minor axis of 42.4 mm and 21.2 mm, respectively, and of the height of 390 mm. The cylinder model was examined...
